Pump retrofitting: New Lease of Life for Old Pumps

For เกจวัดแรงดันnuovafima of the commitment of a mine’s service group to the recommended finest practice in pump management, someday, encountering circumstances of pump component wear and tear is inevitable – a matter of when and never if. And when it does occur, component wear inhibits pump efficiency. It is at that time the place, timeously, mines might have to significantly contemplate retrofitting as a feasible option.
A rational business decision

In this surroundings, the place prices of capital tools costs are rising, replacement could also be a wise enterprise determination. In an advisory focused at mines and different industries, pump OEM, KSB Pumps, recommends retrofitting as a rational enterprise determination: “Retrofitting is a superb alternative to purchasing a brand new product and could be carried out on pumps no matter their meant use. It is equally suitable for industrial, water supply and waste water disposal applications as nicely as for the facility supply trade.”

It is simply pure for mine operators to contemplate acquiring new pumps. New pump fashions meet modern requirements like improved energy efficiency, compliance with new authorized requirements (relating to emissions and safety), prolonged service life and expertise which produces working knowledge. But this will likely not necessitate changing an old pump mannequin, KSB Pumps says, as retrofitting could give an old pump a brand new lease of life, particularly within the following ways:
Save maintenance costs

Reduce energy consumption

Achieve longer service life

Increase system availability

Comply with legal requirements (e.g: TA-Luft, ATEX)

READ: Full-service capability very important for dependable pump provide

Core areas in Retrofitting

The core focus areas in retrofitting are: hydraulic and mechanical modifications to the materials, above and past adjustments to the materials.
Hydraulic modifications

Some of the hydraulic modifications may contain:
Remachining of current impellers

Installation of new impellers for off-design situations

Optimisation of volute casing for off-design conditions

Adjustment of the number of stages (on multistage pumps)

Mechanical adjustments

The following are some of the mechanical adjustments:
Closed bearing brackets improve the smoothness of operation and extend the bearing life

Installation of mechanical seal methods

Employment of cellular floor put on rings to enhance effectivity, rotor dynamics and dry operating properties

Use of optimised supplies

The following are its a few of the materials that a few of the optimised materials which may be used:
Super duplex stainless-steel grades or nickel alloys

Ceramic mineral castings for impellers, put on plates, cowl and casing – for use with finely dispersed, extremely abrasive solutions

Non-metallic rings and bushes

Ceramic plain bearings

Surface coatings
